Quarantine is defined as limiting the freedom of movement of healthy people or animals exposed to a communicable disease for a period up to the longest incubation period of the disease. This is done to prevent effective contact with unexposed individuals. Quarantine can also be applied to ships, aircraft or other modes of transport to prevent the spread of disease. There are three types of quarantine: absolute quarantine, modified quarantine which allows some freedom of movement, and segregation which separates part of an exposed group for special control and observation. In contrast to isolation, quarantine restricts the movements of healthy contacts of an infectious disease. Quarantine was once a common disease control method but has declined in popularity as techniques like early
